On my four-year-old daughter's first trip to Disneyland, she couldn't wait to get on Mr. Toad's Wild Ride. As the car zoomed through the crazy rooms, into the path of a speeding train, and through walls that fell away at the last second, she clutched the little steering wheel in front of her.

When the ride was over, she said to me a little shakily, "Next time, you drive. I didn't know where I was going."
